VEHICLE-SEAT.

SPECIFICATION forming part of Letters Patent No. 283,922, dated August28, 1883.

Application filed January 5, 1883. (N0 model.)

To all whom it may concern:

Be it known that I, JOHN ROBINSON, a citi zen of the United States,residing at Ottumwa, Wapello county, Iowa, have invented new and usefulImprovements in Seats for Vehicles, of which the following is aspecification.

My invention relates to certain new and useful improvements in seats forwagons and other vehicles.

It has for its object to provide an easy automatic adjustment of theseat to a horizontal plane while the vehicle is in motion; and withthese ends in view my invention consists of a seat or seat-framepivotally connected to the side-boards of the body, or to any suitablesupport connected thereto, as will be hereinafter explained; and myinvention further c011- sists of the peculiarities in the details ofconstruction hereinafter referred to and specifically claimed.

In order that those skilled may fully understand my invention, I willproceed to describe the construction and operation of the same,referring by letters to the accompanying drawings, in wh ich Figure 1 isa longitudinal section of one end of the seat and its connection withthe sideboard of a wagon-body, taken at line a; 00 of Fig. 2; and Fig. 2is a transverse section taken at the line y y of Fig. 1, but with theback broken away.

Similar letters denote like parts in both figures of the drawings.

Arepresents the side-boards of the wagonbody, to which, in the instanceI have illustrated, is secured in any suitable manner a seat-frame, Bfrom each end of which extends a vertical leg, 0, the upper end of whichprojects slightly above the horizontal plane of the frame B, and inwhich is formed a bearing, a. The lower end of the leg is formed with afoot, D, the end of which has a slightly-curved toe, E, adapted toconnect with one end of a spiral spring, presently explained. F is thebottom of the seat proper, which may be upholstered in any suitablemanner, and provided with back and arm supports, as may be desired. Eachend of this seat-frame, on the under side, is formed with a curved face,G, adapted to rest on the top surface of the frame B, or, where no suchframe is used, to rest upon the edges of the wagon-body sides, and serveas a rocker.

Extending'inwardly from each end of the frame F are angle-irons H, asmost vclearly shown at Fig. 1, adapted to rest within the bearings a inthe legs 0 to, serve as a pivot, and having the inner end hook-shaped toengage one end of a spiral spring, I, the opposite end of said springbeing connected with the toe E of the leg 0, thus holding the seatFsecurely down to its bearing, and tending by its vertical draft throughthe axis of motion of the seat to bring it to its normal position ofparallelism with the frame or wagon-body.

It will be readily understood from the con struction shown that thelongitudinal vibration of any ordinary vehicle to which my seat may beattached will be compensated for by the positions assumed by the seat,as indicated in broken lines at Fig.2. It will also be un dersto od thatin lieu of attaching the legs 0 to a seat-frame B they may be secureddirectly to the sides of the wagon-frame and the seat connected toproduce same results, and that instead of forming the seat with therocker ends G the pivotal connections between the angle-iron H andbearing a in the leg 0 may be located sufficiently above the plane ofthe seat-frame or wagon-body to permit of the necessary vibration of theseat.

It will be seen that the bearing a is open to permit of any necessaryvertical movement of the angle-iron H within the same.

The spring I may be entirely dispensed with, and the connection betweeniron H and leg G be made a simple pivotal connection; but I prefer toconstruct the parts-as shown to produce the best results.

What I claim as new, and desire to secure by Letters Patent, is

The seat F, provided with rockers G and right-angled downwardly andinwardly projecting iron H, in combination with the leg 0, havingbearings a and toe E, and the intermediate spring, I, substantially asand for the purposes set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

JOHN ROBINSON.
